Weight-limited volume = weight limit / density; payload = min(weight-limited, box); loads = ceil(total / payload). 625 loose cy in 12 cy boxes is 53 loads when the box governs, but haul wet 3,600 lb/cy material and the 40,000 lb limit caps each truck at 11 cy - 57 loads. Weight governs heavy material, volume governs light; pairs with haul-cycle production.

weight_limited_cy = weight_limit_lb / material_density_lb_per_lcy; payload_cy = min(weight_limited_cy, box_vol_cy); loads = ceil(total_lcy / payload_cy).

Governing-payload identity by name (weight-limited volume vs box; loads from total / payload); first-principles min-constraint arithmetic.

The governing-payload logic is public first-principles arithmetic; the box capacity and legal payload come from the truck and the axle/GVW limits.
